TL;DR

This paper introduces a string-theoretic framework to model large N SU(N) Yang-Mills theories in four dimensions, using open-string vertex operators to incorporate non-perturbative brane dynamics and different measures to encode gauge groups and dimensions.

Contribution

It proposes a novel string-theoretic ansatz that captures the dynamics of large N gauge theories via measures in the functional integral, linking gauge groups and dimensions to string measures.

Findings

String theories with different measures describe various gauge theories.

The approach connects brane dynamics to non-perturbative gauge phenomena.

Unified string action for multiple gauge theories.

Abstract

We propose a string-theoretic ansatz describing the dynamics of SU(N) Yang-Mills theories in the limit of large N in D=4. The construction uses in a crucial way open-string vertex operators that describe non-perturbative brane dynamics. According to our proposal, various gauge theories are described by string theories with the same action, but with different measures in the functional integral. The choice of measure defines the gauge group, as well as the effective space-time dimension of the resulting gauge theory.
